摘要： A disc file apparatus which holds a cartridge at both surfaces thereof through a slit formed from an open end to a closed end of a bill-like-shaped cartridge holder, clamps by clampers the cartridge at both lateral sides thereof, and renders the axis of rotation of a pick-up and discharge mechanism shifted from the center of gravity thereof so as to regulate rotation of the cartridge holder by a stopper in a range of an angle of 180.degree., whereby when the catridge is turned over or even when the same is subjected to an impact from the exterior, the cartridge is reliably held so that there is no fear that the rotational position thereof is shifted. The disc file apparatus uses linear ball bearing at each movable part and makes stand-by the utmost end of the clamper as close as possible to a stocker or a recording and reproducing system, thereby improving the processing speed as a whole, and furthermore temporarily makes stand-by the cartridge discharged from the recording and reproducing system just above an insertion and discharge port thereof by a transfer mechanism, thereby enabling a processing time to be reduced when a plurality of cartridges are continuously fed to the recording and reproducing system.

摘要： An inserting and retrieving mechanism of a "Juke Box" type disc memory device includes a movable body which has pushing members adapted to push a cartridge into a stocker or a recording and reproducing device of the disc memory device and a pair of clampers adapted to pull out the cartridge from the stocker or recording and reproducing device in association with engaging recesses formed on the cartridge, a driving means for opening and closing the clampers through a toggle means arranged symmetrically about the driving means, a first position sensor provided on the inserting and retrieving mechanism for detecting a position of a rear end of the cartridge when it reaches a position in which the clampers are ready to clamp the cartridge and a second position sensor provided in the stocker and/or the recording and reproducing device for detecting a position of a front end of the cartridge when it reaches a position in which the cartridge is ready to be released. The inserting and retrieving mechanism may have a pair of cartridge holding portions so that a pair of cartridges are to be handled, simultaneously.

摘要： A disk-storage device comprising a conveying mechanism having a plurality of clutching sections for clutching cartridges; a plurality of recording/reproducing units for recording and reproducing information on and from disks in the cartridges; and a plurality of lodging shelves for lodging cartridges. The number of recording/reproducing units and of lodging shelves is the same as the number of clutching sections, these three categories of components being arranged in the same positional relationship. They are all contained in a case having cartridge-supply/discharge openings through which cartridges are put into and taken out of the device. To enable a plurality of cartridges to be simultaneously held by the clutching sections of the conveying mechanism, a plurality of loading mechanisms temporarily hold cartridges, adjusting their positions accordingly. The cartridge-supply/discharge openings and the loading mechanisms are arranged in the same positional relationship. The device further comprises a divisional recording means adapted to time-divide information from the exterior and to distribute the information thus divided to the recording/reproducing units so as to record it on the disks in the cartridges, and a synthetic reproduction means adapted to synthesize information recorded on the disks by the recording/reproducing units in predetermined equal periods and to transmit it to the exterior.
